Similar Species: Geranium richardsonii and G. caespitosum are both vegetatively similar, but G. richardsonii has whitish flowers with spreading petals 12-20 mm long and G. caespitosum has purplish flowers with spreading petals that are broader than those of G. dodecatheoides and hairy halfway up the adaxial surface.

Distribution: New Mexico: Lincoln County. Three Rivers Canyon on the western slope of Sierra Blanca and east of Capitan Gap in the Capitan Mountains.

Remarks: This is the only geranium in North America with reflexed petals although seven species in Europe and Asia have this feature. It was discovered in 2010 by Patrick Alexander while hiking the Three Rivers Trail (Tr. 44) on the Lincoln National Forest.

Conservation Considerations: This species is presently known from two localities in the Lincoln National Forest. The very small size of the known populations make it vulnerable to stochastic extinction events. Additional searches are needed.
